Method for identifying the condition of an energy accumulator
First Claim
1. Method for detecting the status of an energy storage means (1), wherein actual values (2, 3, 4) are determined, wherein said actual values (2, 3, 4) are supplied to an estimation routine, characterized in that the estimation routine includes a model-based parameter estimator and a model-based filter (7), wherein the actual values (2, 3, 4) in a decoupled fashion are supplied to the model-based parameter estimator (5) and the model-based filter (7), wherein the model-based parameter estimator (5) and the model-based filter (7) are subordinate to a monitoring level (12), wherein values (8, 11) obtained in the model-based filter (7) impacts a predictor (17) that extrapolates the behavior of the energy storage means (1).

Abstract
A method for detecting the status of an energy storage means (1) provides that its actual values (2, 3, 4) can be supplied to an estimate routine (5). The actual values (2, 3, 4) can be supplied in a decoupled manner to a model-based parameter estimator (5) and to a filter (7), which are subordinate to a monitoring level (12). Parameterization values (8, 11) obtained are supplied to a predictor (17) that extrapolates the behavior of the energy storage means (1).
